Subject: Pietenpol-List: things about the straight axelI don't know about Jack Phillips but I have no trouble making consistently smoothlandingswith my straight axel gear now that I got my vision corrected from 20/ 800. ;)There are several factors that make a straight axel gear a truly excellent landinggear. There is no toe-in, out, or camber--the gear tracks true and straight. You can make the ride stiffer by rewrapping your bungees tighter or you can rewrapthem fora more cushy ride. Tire inflation pressure can make a big difference in ride quality but a more firmwheel givesless roll resistance on takeoff. Also with the straight axel you can have a wingwalker do chin ups on the axel whenflyingair show work.

Has the straight axle group stayed with the plans??? The dimensions called forseem real narrow. I am about ready to turn my fuselage upside down and start building.I had a Luscombe that was a little narrow but handled great. It was around72". How wide does the Piet wind up being? The drawings say the structureis 42" I think, add brakes and wheel I would say around 54"??

Has anybody here ever mounted a Model A radiator between the landing gear legslike on so many other 1920s airplanes?Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Mike Cuy = Clark Gable?

I made mine 6 feet wide.Jack PhillipsNX899JPRaleigh, NC-----Original Message-----

Thanks Jack you just pushed me over the edge. That 42" was the width of the framework....almostlike a glider landing gear. I want to be able to fly in crosswindand 6 feet tread will sure help about getting a wing up. A friend came overlast week on his Champ and had a good crosswind. He didn't hold his wing down...windgot under it and he almost got the tip on the grass. He ran over 100feet all out of shape. Just was hid day. He is a lot more careful now.--------Jerry Dotson59 Daniel Johnson RdBaker, FL 32531Started building NX510JD July, 2009Ribs and tailfeathers doneusing Lycoming O-235Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Sat, 24 Apr 2010 17:33:55 -0700 (PDT)

One more consideration with the straight axle gear is "ramp appeal". It will set the airplane apart from EVERYTHING else on the field.Greg Cardinal----- Original Message -----

>I made my gear from the Glider and Flying Manual with Big wheels, true to drawings.I will say that the gear will swing front and back between the wood struts as each wheel encounters bumps (resistance) on a grass strip turning her from side to side. So tap dancing on the rudder was a workout. I only felt this during takeoff and not so much during landing.

Kerri Ann,No doubt, you are aware that most builders now engineer some sort of slidebar to keep the axle from swinging back and forth. Would you say that isoptional?Gary BootheCool, CAPietenpolWW Corvair ConversionTail done, Fuselage on gear18 ribs done-----Original Message-----

As long as you are displaying your correct "N" number in minimum 2" letterson the tail, you can paint whatever series of letters or numbers whever youwant on the airframe, as long as a series of numbers doesn't start with theletter "N".My reg # is N799B (NX799B, thank you very much!) but I just painted "799" onthe wings 'cause it felt nostalgic, and doesn't give more info to thegeneral public than necessary, and is perfectly legal.Douwe________________________________________________________________________________Subject: Pietenpol-List: Re: things about the straight axel

I agree. Make sure you fully capture the axle in all plane axis.If I did this again I would make a side plate with a slot in it for the axle toride up and down in and to remove the back and forward swing. I would also notdepend on a safety cable to stop the axle travel do to a bungee cord failurewhereby letting the gear legs dig into the ground.Seen many ways of doing this, made up with tubing or sheet stock. But I would notdo it with just bungee cord wrapped around a straight again.Just my 2 cents."Keep the Dream"--------http://westcoastpiet.com/yesterday_wings.htmRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 29 Apr 2010 07:36:24 -0400 (GMT-04:00)
